    Comparison of Atmospheric and Lithospheric Culturable Bacterial Communities from Two Dissimilar Active Volcanic Sites, Surtsey Island and Fimmvörðuháls Mountain in Iceland 
    Daussin, Aurélien; Vannier, Pauline; Ménager, Marine; Daboussy, Lola; Šantl-Temkiv, Tina; Cockell, Charles; Marteinsson, Viggó Þór (2023-03-06)
    Surface microbes are aerosolized into the atmosphere by wind and events such as dust storms and volcanic eruptions. Before they reach their deposition site, they experience stressful atmospheric conditions which preclude the successful dispersal of a ...

    Microbial Metabolism of Amino Acids—Biologically Induced Removal of Glycine and the Resulting Fingerprint as a Potential Biosignature 
    Schwendner, Petra; Riedo, Andreas; Melton, Daniel J.; Horvath, Peter; Lindner, Robert; Ehrenfreund, Pascale; Beblo-Vranesevic, Kristina; Rettberg, Petra; Rabbow, Elke; Westall, Frances; Bashir, Alexandra; Moissl-Eichinger, Christine; Garcia-Descalzo, Laura; Gomez, Felipe; Amils, Ricardo; Marteinsson, Viggó Þór; Walter, Nicolas; Cockell, Charles S. (2022-04-04)
    The identification of reliable biomarkers, such as amino acids, is key for the search of extraterrestrial life. A large number of microorganisms metabolize, synthesize, take up and excrete amino acids as part of the amino acid metabolism during aerobic ...

    Taxonomic and functional analyses of intact microbial communities thriving in extreme, astrobiology-relevant, anoxic sites 
    Bashir, Alexandra Kristin; Wink, Lisa; Duller, Stefanie; Schwendner, Petra; Cockell, Charles; Rettberg, Petra; Mahnert, Alexander; Beblo-Vranesevic, Kristina; Bohmeier, Maria; Rabbow, Elke; Gaboyer, Frederic; Westall, Frances; Walter, Nicolas; Cabezas, Patricia; Garcia-Descalzo, Laura; Gomez, Felipe; Malki, Mustapha; Amils, Ricardo; Ehrenfreund, Pascale; Monaghan, Euan; Vannier, Pauline; Marteinsson, Viggó Þór; Erlacher, Armin; Tanski, George; Strauss, Jens; Bashir, Mina; Riedo, Andreas; Moissl-Eichinger, Christine (2021-02-18)
    BACKGROUND: Extreme terrestrial, analogue environments are widely used models to study the limits of life and to infer habitability of extraterrestrial settings. In contrast to Earth's ecosystems, potential extraterrestrial biotopes are usually ...

    A total of 219 metagenome-assembled genomes of microorganisms from Icelandic marine waters 
    Jégousse, Clara; Vannier, Pauline; Groben, René; Glöckner, Frank Oliver; Marteinsson, Viggó Þór (2021-04-02)
    Marine microorganisms contribute to the health of the global ocean by supporting the marine food web and regulating biogeochemical cycles. Assessing marine microbial diversity is a crucial step towards understanding the global ocean. The waters surrounding ...
